To what voices shall we listen first? Stand on the shore of a lake set like an azure gem among the bosses of green hills. The patter of rain means an annual fall of four cubic feet of water on every square foot of it. It weighs two hundred and forty pounds to the cubic foot, one hundred million tons on the surface of a little sheet of water twenty miles long by three wide. Now, all that weight of falling rain had to be lifted, a work compared to which taking up mountains and casting them into the sea is pastime. All that water had to be taken up before it could be cast down, and carried hundreds of miles before it could be there. You have heard Niagara's thunder; have stood beneath the falling immensity; seen it ceaselessly poured from an infinite hand; felt that you would be ground to atoms if you fell into that resistless flood. Well, all that infinity of [Page 250] water had to be lifted by main force, had to be taken up out of the far Pacific, brought over the Rocky Mountains; and the Mississippi keeps bearing its wide miles of water to the Gulf, and Niagara keeps thundering age after age, because there is power somewhere to carry the immeasurable floods all the time the other way in the upper air. But this is only the Alpha of power. Professor Clark, of Amherst, Massachusetts, found that such a soft and pulpy thing as a squash had so great a power of growth that it lifted three thousand pounds, and held it day and night for months. It toiled and grew under the growing weight, compacting its substance like oak to do the work. All over the earth this tremendous power and push of life goes on--in the little star-eyed flowers that look up to God only on the Alpine heights, in every tuft of grass, in every acre of wheat, in every mile of prairie, and in every lofty tree that wrestles with the tempests of one hundred winters. But this is only the B in the alphabet of power. Rise above the earth, and you find the worlds tossed like playthings, and hurled seventy times as fast as a rifle-ball, never an inch out of place or a second out of time. But this is only the C in the alphabet of power.
